Bees contribute to food production through pollination by transferring pollen from the male part of the flower (anther) to the female part (stigma) of the flower. This process fertilizes the flower, allowing it to produce fruits and seeds. Approximately 75% of the world's crops rely on pollinators like bees to reproduce. Without bees, many plants would not be able to produce fruits and vegetables, leading to a decrease in food production and biodiversity.
